WRINGER.

Application filed November 11, 1920A Serial No. 423,225.

This invention relates to wringers, such as are ordinarily used in connection with power washing machines. Among the objects of my invention are: to make the wringer separable from the reversing gear casing; to malte both wringer rolls readily removable from t-he wringer frame; to construct the driving shaft of the driving roll in sections so that the roll may be readily separated from the driving gear; to improve upon the direction reversing mechanism; to provide means for automatically shifting the inclination of the drain plate upon reversing the direction of rotation of the wringer rolls; to releasably secure the top wringer roll in the pivoted top section of the frame; to provide an improved shaft bearing; to provide improved water drainage mechanism for a wringer; to pro vide improved locking mechanism for the pivoted top of a. wringer; and such further "objects, advantages andcapabilities as will later more fully appear.

My invention further resides in the combination, construction and arrangement of parts illustratedin the accon'ipanying drawings, and while I have shown therein a preferred embodiment I desire the same to be understood as illustrative only and not as limiting my` invention. j j

In the accompanying drawings:

Fig. 1 is an elevation of a wringer embodying my improvements.

. Fig. 2 is an inner face view of the gear casing head, showing the same with wringer detached.

Fig. 3 is an end view of the wringer, showingthat face which is adapted to be connected to the face shown in Fig. 2.

Fig. 4: is a broken plan view, on a larger scale than Fig. 1, of my improved wringen t showing the top portion released and turned over to expose the parts beneath.

Fig. 5 is an outside end view of the wringer.

Fig. `6 isa substantially central, vert-ical section of the structure shown in Fig. 1.

Fig. 7 is a. broken, vertical, longitudinal, substantially central section through the structure shown in Fig. 1.

My new wringer comprises the separably connected gear head II and wringer IV. The head I-I comprises the gear casing 1 in which the driving gear and wringer reversing mechanism are located and the supporting sleeve 2 `by means of which the whole structure is supported upon a shaft connected with a washing machine. Slidably mounted in the head as shown more clearly in Figs. 1 and 7 is the locking bolt 3 operated by means of the handled and crank 5, which locking bolt is adapted to engage perforations in the flange of a member suitably connected to the wash-A ing machine.

Rotatably mounted in the head II is a shaft 6, an end of which is suitably notched to engage the upper end of a driving shaft appropriately connected to the driving mechanism. Near its central part, this shaft is provided with a non-cylindrcal part 7, shown in this drawing as being squared. On this squared portion slides a. sleeve 8, having projections `9, or the equivalent thereof, upon its ends. Centrally, this sleeve is provided with a reduced portion which forms a groove 10 in which is located a block 11, shaped to fit closely against the curved face of the sleeve, and provided in one` face with a slot in which operates a pin 12 on a disk 13 connected with the reversing handle 1&1. Loosely mounted on shaft 6 is a pair of gears 15 and 16, which are adapted to alternatively transmit motion to the gear 17 mounted on the inner end of shaft 18 and secured thereto. The faces of gears 15 and 16,

t facing sleeve 8, are provided with notches or Stu projections, to engage the corresponding parts 9 of the sleeve. It will therefore be seen that when the crank 14; is turned from the neutral position shown in Fig. 7 sleeve 8 will be forced either upwardly or downwardly into engagement with one or the other of gears 15 and 16, and therefore that, when shaft 6' is driven, gear 17 and shaft 18 will be caused to rotate in one or the other direction.

an aperture 19, which is non-cylindrical in form, and a flange which has its edge notched to form teeth 20, thereby providing a. driving `gear for co-operation with the gear 21 on apertures 2a and the wringer with a pair of apertures 25 adapted to register with each other, so that the head and wringer can be The inner end of shaft 18 is formed with .lin

loss' resulting from such breakage This sup-l ply parts 'also' facilitated by `the ease with which the wringer yrolls may be removed and replaced, either in the event of wearing outlof the rolls or the breaking of one or the other ofthemlor of the frame.

y rlhe upright end members of the wringer are connected by a transverse connecting member 27, comprising a ridge 28, or the equivalent thereof, and a pair of lateral meinbers', sloping downwardly away from the ridge'.y v Supported loosely and removably on thev ridge 28, isa drain plate or board 29 which is itocka'ble to throw the water to one sideor the other of the wringer. T his drain plate l29 has a pair of end extensions 30 and 3l reaching out into relatively narrow ways formed by the `spaced apart upright members' ofthe frame anditending to hold the drain platek loosely in proper'position'. The opposite sides or vertical walls of .these narrow ways arev provided with recessed ways 3l for Vreceiving angularly shapedroller casing members hereinafter described. As shown clearly infFigures 5 and 7, vone end of the frame is provided with an extension 32 substantially cradleshaped. The end of extension ,'31 has an upwardly extending toot-hed projection `32. l,This projection32 has a dependingg"l toe or lng y32a adapted rockably l and loosely to in the cradle of the extension 32"; The 'teeth' vof `projection 32 may take the form of a segment of agear as shown in Figure 5,. On the end of shaft 23 is av sleeve 33` which hasa projectiond which may take the form of a segment of a gear, and which cooperates with the projection 32. @n the opposite side of the sleeve 33 from projection 34 is a hollow threaded projection 85,' in which is mounted a friction meinber 35 which may have its tension on shaft 23k varied by means of a threaded! headless bolt 37. `This makesfit possible to have the proper amount of friction between shaft'23 andfblock 36 so thatI drain board 2 9 will be positively rotated-ashort distance in an opposite direction from shaft 23, and yet the friction does not need te be'ercessive at any time, as the saine may beadj usted in accordance withthe amount of wear which occ-urs. It will be seen from the above that if clothingis being fed into the wringer from the left side as shown in Fig. 6 the drain 'platewill occupy the ,position there'shown. lf., however, the wringer is reversed and the-roll starts to move in the opposite direction, drainplate 29 will lessblock 36, which may be made of leather,

wood, or the like, becomes worn to such an extent that the drain board fails to tilt. fn this event, a slight turn of bolt 3T will cause a suflicient chanee in pressure to niiike the drain board react again as it should. lt will also be evident that the rib fill along the top of the wringer casting 2T upon which the water plate rocks, acts as a dam to heep "ihf water from ruiming back under the plate. In addition, this rib 2S also acts as u support to take the strain in case the lower roller should become wrapped with fabrics and cause an undue pressure downwardly on plate 29. rllius will be seen that this rib has a threefold purpose, firstly, it acts :is a pivot for the drain plate 29, secondly, as a dam to keep water from ruiming back under the plate, and, thirdly, as a support for the plate. It will also be evident that the high sides and ends as shown in plan view in Figure l about the drain plate trunnioii are pro vided to keep the water from running out at these points. One of the main advantages of this construction resides in having the plate 29 loosely and detachably mounted in this position so that when the wringer is released the lower roller may be lifted out and then the drain plate 29 may be lifted outlm Pivoted tothe upright end members of the frame is a pair 0f cross members 3S and 39, to which is pivoted a cap plate 40, having a pivotal member or members ell, flattened as shown in Fig. 4- and as indicated by dotted line 42 in 5. lt will be seen that when the'cap plate Ll() is iu the position shown in Figz the member or i'i'ieinbers ll will engage the hooks at the upper ends of inem bers 43 to hold the cross bars 38 and 3:) down in the position intended for wringing, but that when cap plate Ai() is turned to the position shown in Fig. l the pivots will be released from the hooks so that the cap plate, cross bars, and upper rine'er roll :nav be turncdron the pivots connecting the cro lars with the end members of the frame. This structure makes it very easy to release the tension on the rolls, in the event the hand should get canght between them or clothes get bunched in going through the wringer. It also makes it easy to open up the wringer for `the purpose of taking out the wrinficr rolls and drain plate. i

Each wringer roll shaft is provided adjacent each end with an anti-:h 'iction device, the-structure of which is shown iuost clearly in Fig. 7. This comprises a sleeve llvlwhich closelyy fits Vthe shaft but is easily rotatable thereon, and has one end reduced in diameter toV form a shoulder, approximately centrally ot the length oit the sleeve. Another sleeve 45 is iitted snugly to the exterior surface et the reduced portion oif sleeve et and is so proportioned as to leave a groove at its inner end for the reception et roller members such as balls or cylinders LlG. Around these roller members is arraneed a roller casing 1li', which as shown in Fig. o, is preferably angular and adapted to lit in the recessed ways Si termed in the opposite sides ot the open mounted spaced apart upright end members whereby te prevent` the rotation ot the casings in the end members ot the iframe while at 'the saine time permitting,` the tree reino Tal ot the bearing casingl by lifting,1 them out vertically. rejecting from one :tace of each oil" cross bars 38 and 89 is a pair of lugs d8, having perforations in their ends 'lfor the reception olf Cotter pins al) or the like, by means oit which 'the bearings tor the upper wringer roll are held inposition in the cross bars, so that the upper roll will he retained assembled with the upper or swinging` element ot the ilrainc. lt will be seen that` it' it is desired to remove the upper roll this 'is easily accomplished by opening the wringer as shown in Fig. l and removing the cott-er pins i9 whereupon the roll can be lifted out. It desired, an end ot one of the shafts 22 and Q3 may bc extended sul'iiciently to receive a wringer handle, if tor any reason it is desired to maire use ot saine. 1When a handle not attached to this end the same will be covered by a hnishing` and protecting cap 50 as showniii'i Fig. i'.
